LASER PATTERNING OF CYLINDERS FOR PRINTING, IMPRINTING, EMBOSSING, AND INVERSE OFFSET, FOR 3D PATTERNING

摘要

The present disclosure relates to a method for making high precision patterned cylinders with arbitrary patterns and without a seam. In particular it relates to a method forming a 3D nano printing surface with non-binary features on a cylindrical form forming a seamless 3D latent image in a resist layer on a cylinder, developing the 3D latent image and directionally etching away the developed resist and a portion of the exterior surface of the cylindrical to a 3D onto the surface of the cylindrical.
